As more airports opened in Volcanic ash stricken Europe and stock markets rallied on strong corporate earnings, the oil prices escalated 84 a barrel in Asia as stock markets on Wednesday. This alleviated fear of reduced demand for crude.

The standard crude for June delivery was increased by 48 cents at $84.33 at late afternoon Bangkok time in electronic trading on the New York Mercantile Exchange. It escalated to 72 cents to settle at $83.85 a barrel on Tuesday.

Oil prices had frozen over the last two weeks, hitting $87 a barrel earlier this month. The demand for jet fuel has been very low due to the volcanic eruption in Iceland that shut down air traffic in much of Europe since last week.

Though some of the European airports remained shut, but flights have now started landing in cities such as London and Paris. The technology shares also boosted as Apple Inc., surpassed expectations with a 90% jump in net profit for the most latest quarter.

Heating oil mounted 1.8 cents to $2.199 a gallon and gasoline escalated 0.9 cents to $2.29 a gallon. But natural gas went down 1 cent to $3.965 per 1,000 cubic feet.
